Lower frequency of adiposity (general and central) was found with increasing age. After adjustment, the prevalence of both outcomes was significantly higher in women aged 70-79?years and hypertensive.Conclusions The results of this study confirm the need to establish nutritional status monitoring and direct obesity prevention and control interventions in programs to promote health and quality of life of older adults and those in the stages prior to old age.In order to explore the effect of pretreatment on corn straw degradation and biogas production, corn straw was pretreated with mixed microbes and composting at 30°C for 14&nbsp;days. The characteristics of material were measured and analyzed in the pretreatment process. Then, the pretreated and untreated corn straw was digested by anaerobic fermentation. Gas production and methane content of corn straw were analyzed. The results showed that the biological pretreatment process with mixed microbes could accelerate the degradation rate of straw and increase the degradation efficiency of lignin. The pH value of material was more stable, and the content of organic matter in the material was higher in the pretreatment process of corn straw with mixed microbes. The Scanning Electron Microscope (SEM) images showed that the structure of the lignocellulose was changed by mixed microbes, increasing the exposed area of cellulose and hemicellulose, which was beneficial to improve the utilization efficiency of straw. The degradation rates of hemicellulose, cellulose and lignin were 44.4%, 34.9% and 39.2%, respectively, after the pretreatment process with mixed microbes. Pretreatment was more helpful to increase the methane content in the anaerobic fermentation process of corn straw pretreated with mixed microbes, and could also shorten the fermentation period.Background Electronic cigarette or vaping product use-associated lung injury (EVALI) is a serious public health concern with substantial morbidity and mortality, particularly in young individuals. Purpose To evaluate chest radiographic and chest CT findings of EVALI in the pediatric population. Materials and Methods This was a retrospective study of children who presented to a tertiary pediatric hospital from December 2018 to December 2019. Patients fulfilled the Centers for Disease Control and Prevention criteria for EVALI and had chest radiographs and CT images available at initial presentation. Two pediatric radiologists independently reviewed imaging for pattern, distribution, and extent of pulmonary abnormalities, as well as for extrapulmonary abnormalities. Clinical information, management, and outcomes were reviewed. Interobserver agreement was measured with Cohen κ coefficient. Results Seven male patients (50%) and seven female patients (50%) (mean age, 16 years; range, 13-18 years) were evaluated. Al-associated lung injury is characterized by bilateral symmetric ground-glass opacities, consolidation, and a lower lobe predominance at CT. © RSNA, 2020.Background Spinal digital subtraction angiography (DSA) exposes patients and operators to substantial amounts of radiation. Antiscatter grid (ASG) removal is used to decrease radiation exposure but may reduce image quality. Purpose To determine whether ASG removal during spinal DSA in adults reduces radiation dose while maintaining diagnostic image quality and whether dose reduction is related to body mass index (BMI). Materials and Methods This Health Insurance Portability and Accountability Act-compliant prospective study included adults undergoing spinal DSA between January and December 2016. Each procedure included an additional angiographic acquisition performed twice, once with and once without ASG, either documenting the artery of Adamkiewicz (no pathology group) or the condition leading to the procedure (pathology group). Dose differences between study acquisitions and the influence of BMI were evaluated via paired t test. Two neurointerventionalists blinded to acquisition protocols were asked to indeon Antiscatter grid removal during spinal digital subtraction angiography decreased participants' radiation exposure while preserving diagnostic image quality. © RSNA, 2020.Background Paclitaxel drug-coated balloon (DCB) catheter angioplasty is the preferred treatment for revascularization of femoropopliteal lesions in peripheral artery disease, but mortality is a safety concern. Purpose To assess 2-year efficacy and safety of DCB angioplasty compared with conventional balloon angioplasty (also known as plain old balloon angioplasty or POBA). Materials and Methods This prospective, multicenter, randomized controlled trial enrolled consecutive participants with symptomatic superficial femoral and/or popliteal artery disease at 11 German centers between September 2015 and December 2016. Participants underwent DCB angioplasty or conventional balloon angioplasty. Primary outcome of 6-month late lumen loss showed superiority of DCB angioplasty over conventional balloon angioplasty. Evaluation at 2 years included secondary outcomes of primary patency and target lesion revascularization (TLR) estimated with Kaplan-Meier analysis, clinical and hemodynamic improvement, quality of life, tnal balloon angioplasty participants died (risk ratio, 0.48; 95% CI 0.04, 5.10). Conclusion At 2 years after paclitaxel drug-coated balloon (DCB) angioplasty, primary patency and freedom from target lesion revascularization remained superior compared with conventional balloon angioplasty. DCB angioplasty resulted in sustained clinical and hemodynamic improvement with no increased risk of mortality. © RSNA, 2020.Background The risks associated with MRI in individuals who have implanted cardiac devices are thought to arise from the interaction between the implanted device and static, gradient, and radiofrequency magnetic fields. https://www.selleckchem.com/products/tulmimetostat.html Purpose To determine the relationship between the peak whole-body averaged specific absorption rate (SAR) and change in magnetic field per unit time (dB/dt), maximum specific energy dose, imaging region, and implanted cardiac device characteristics and their function in patients undergoing MRI. Materials and Methods This prospective observational cohort study was conducted from October 16, 2003, to January 22, 2015 (https//ClinicalTrials.gov, NCT01130896). Any individual with an implanted cardiac device who was referred for MRI was included. Clinical MRI protocols without SAR restriction were used. Exclusion criteria were newly implanted leads, abandoned or epicardial leads, and dependence on a pacemaker with an implantable cardioverter defibrillator without asynchronous pacing capability. For each MRI pulse sequence, the calculated whole-body values for SAR, dB/dt, and scan duration were collected.
